zoom meeting I have an issue of zoom meeting sharing my screen of iPad pro 12.9 3rd with iPadOS14

I am also having the same problem and this is creating a lot of issues for educators who rely on their iPad to teach their students remotely.

I've also updated to iPadOS14 this past weekend and today I've been having issue sharing my iPad Pro screen via Zoom when I connected my iPad Pro (with iPadOS14) to my Zoom meeting.

Can I please downgrade my iPadOS so that I can use it as soon as possible? This is really frustrating! Please help!

AFAIK, AirPlay Mirroring does not support mirroring from one iOS device to another. Instead, you can mirror your iPad to either an Apple TV or an AirPlay-enabled HDTV.

Same thing here. I'm TAing this semester at UC Berkeley. I upgraded my iPad pro to ipados 14 last Thursday and my Friday's discussion section was totally ruined. When I shared my screen in Zoom and switched to another app, it just froze and disconnected. I tried a few times and resulted the same. I had to show the empty slides on my laptop and just spoke. SUPER annoying and awkward

My guess is you need to let Zoom support know. They likely need to update their iOS app for iOS and iPadOS 14.
